Description_x000D_ Application_x000D_ Deoxyguanosine (dG) is a purine nucleoside that upon sequential phosphoylation (kinases) forms dGTP which is used by DNA polymerases and reverse transcriptases to synthesis DNA(s). Deoxyguanosine is the most electron rich of the four canonical bases and includes many nucleophilic sites which are susceptible to oxidative damage. This makes deoxyguanosine and its oxidized derivatives useful reagents to study mechanisms of oxidative damage to nucleosides and nucleotides._x000D_ Packaging_x000D_ 1, 5 g in poly bottle_x000D_ 25, 100 mg in poly bottle
